Extreme pro not recognised

My 256gb drive is no longer recognisable in file manager programs. tried several computers and its not showing. Scandsk wont scan the drive as its not there. computer management win11 show the removable disk but no partitions present.
Im not that techie but reckon i can follow some instructions if any of you clever folks can suggest something.
thanks in advance.

Hi @john6 ,

Have you opened a Support Case? If not opened, for more information, please contact the SD Technical Support team for best assistance and troubleshooting:

thanks… yes i have and now waiting on a RMA number. seems to take a while.

Any update?

yes replacement arrived so all good.

I am glad to hear that.

the trick is do not format the drive. i think it deletes files in the front directory which are needed. if you have the receipt your solution is get a replacement. i couldnt get anything to work to make any computer recognise the drive as having a partition, which meant we dont have anything to work with… Sandisk are a top company so hopefully they will serve you well with the replacement.
